Ok so recently did the opti on my car and while I was in there I ripped out the air pump and all the other crap . I didn't cut off the things front he exhaust manifolds yet just have it capped off with a rubber cap . I wanna cut it off and plug it properly I just don't know why size thread I need Ina bolt to plug it . I saw someone do it on an impala and they used a cap but I pretty sure the camaro and firebird exhaust manifolds are different . Any help highly appreciated . Thanks guys
